Ancient Humans in Rainforests — Prehistoric Africa Rewritten

Ancient humans in rainforests: a 150,000-year-old West Africa discovery rewrites prehistoric Africa and early human survival. This science podcast episode reveals how a Côte d’Ivoire discovery transforms rainforest human history and human evolution discoveries. Understand how ancient humans lived deep in tropical forests, used yams, and reshaped what we know about human origins in Africa. What You'll Learn: Why the new Côte d’Ivoire site provides the earliest secure date for sustained human rainforest life around 150,000 years ago. How more than 2,300 stone artefacts—78% made from locally sourced quartzite—reveal advanced early human survival strategies in dense forests. How starch grain analysis identified yam residues, giving the earliest direct evidence of tuber exploitation in Africa. Why the long-standing belief that ancient humans avoided rainforests in prehistoric Africa is now being overturned by hard data. What West Africa archaeology can tell us about technology, mobility, and resource use in challenging rainforest environments. How rainforest human history fits into broader human evolution discoveries and models of human origins in Africa. What this discovery suggests about ancient climate, ecosystems, and where we should look next for hidden human history. How this science podcast episode connects cutting-edge lab work with on-the-ground excavation to tell a new story of early human survival.
